Be it known that I, CI-IARLns P. vKIMMEL, citizen .of the UnitedStatesresidingat Gary,.India-na, in thev county of Lake and State ofIndiana, lia-ve'invented certain new Devices, of lwhich the4 followingis a-v speciiicatio'n. f

My inventioirrelates to; clamping means y it'or railroad rails andparticularly toen` improvementon the construction ydisclosed 63,068,inea october-17,1925. An object inthe present construction is to providea simplified holding device adapted for use in connection with metalties of the .type'disclosedin the copending applications referred to.Thetie particularly contemplated is onev vof hollow, metallic form andprovided with an openfslot in itsv upper surface. In the improved formof my holding device, I- provide ,a clamp having a head overlying theraily base, ahbody of tapered form, a foot adapted to enter a'recessinthe tie anda toeadapted to be distorted( The y' only other essentialelement is a key of gen.- erally `I-shapedcross section, adaptedfforwedge engagement with thebody'of.. the

clamp and further adapted to. be held against escapebyy reason of the.distorted toelo`f .thefclamp1 f'f 1 A clamp of thekindhereindlsclosedfpos-l sesses numerous advantages due tothe :relativesimplicity of the parts,.tliere being but two of such parts constitutingvthe clamp.

Of course, I may see fit to construct the key in two. parts tofacilitate engagementwith the tie, in which case there' will be threeparts., The -form of the holding connection is such that the parts maybemassive in construction, thus avoiding anyfpossibility of displacementof the 'rail due' to -i'ailure of the clamp.. The holding connectionispermanent and positive and yet the clampmay easily be dis-engaged forreplacement of rails if desired. U f

The invention will be more readily understood by reference f to the'accompanying drawings, in which d f Fig. 1 is a plan view of a portionof a tie and rail with my improved Vfastening device associatedtherewith, one form ofthe Vfastening device in which tliekey iscom-1posed oftwo parts beingshown `in ythe'right.- and portion 0f 11h@ YQW?@.1151 another. .form

In theldrawings, it will be .seen that the t-ie,10,vis of Vhollow iormand-is ,provided with a slot, l1 in the upper Wall thereof, this y slotextending from end to end of the tie.

In theillustration, the rail isshown;

resting on a tiev plate, 14, of generally arcuate form. Where required,I willl also Vprovide suitable insulation for the rail.

The rai-l clamp comprises a head, 15, hav-v ing a portion overlying therail base, a neck,

16, and a body, 17, which as best'shown in Fig. 4, isbifurcated,-theupper surfaces, 18,

.of which bifurcated portions being inclined downwardly and outwardly.On the klower surface of cachot the bodyportions, I pro- '.'videa,foot19,adapted to enter-the notches,

13, in the tief and lto abut against an-:oute'r wallthereoig Thus theclamp is held against lateral movement by positiv-e engagement betweenmetal parts, and the area of contact between such .parts may be lsuchasto posi- Y tively preventspreading of the rails. i Themeans' fori'holdingdown' the clamp consistsvoakey which may be of two parts, 20,21,' together? constituting aymember of generally I-shape-d crosssection; or the key .may be composed oi one piece as shown at 22 inFigures 1 andY 7 In the latter case, the vkeyfmust,.of=recessity, beslid inwardly from the end of the tie. Where composed of two pieces, thekey may bey inserted at anyv point between the ends of the tie bylirstinserting one part, moving it to position and then insertingl thecomplementary part and moving it into position. vThe `key is providedwith side recesses or slots, 2 3, the upper walls of which slots areangularly disposed asat 24, to provide an inclined surface adaptedA toContact with'the inclined surface,nl8, Qn'theperts. ofthefbody. vThusthe key may be driven by means of a lianr mer or sledge into positivewcdging engagement, the under walls, 25, of the side slots underlyingthe material adjacent to the open slot, 1l, in the tie.

When suitably positioned, the key may be held in place by bending up thetoe or eX- tremity, 26, of the body, into the position shown in dottedlines, in Fig. 2. Thus the parts are firmly held in an immovableposition without possibilit-y of displacement eX- cept by distorting themetal.

lf it becomes desirable to remove one or both of the clamps, a wedge ordrift pin 2"?, shown in dotted lines in Fig. 2, may be inserted in theopen space at the endL of the key and the key may thus be driven off andthe parts released; or the distorted toe may be driven down to itsoriginal position as a preliminary to the application of the displacingwedge.

lt will be-noted that the holding connection is extremely iirm, rigidand unyielding; that the parts are of extreme simplicity and that themeans employed adapt themselves to simple and economical laboroperations in installation. l have illustrated but one of severalmodifications that might be made without departure from the spirit of myinvention, and l do not wish to be limited except as indicated in theappended claims.
